Specification of Letters Patent. I Patented Mal. 23., 1915.

Application filed August 22, 1914. Serial No. 858,161.

T all whom it may concern:

Be it known that 1, WILLIAM BUOKLEY, a

citizen of. the United States, residing at Ashland, in the county of Ashland and State of lVisconsin, have invented certamnew and useful Improvements in Means for Preventin Incrustation of Boilers; of which the following is a specification.

My invention relates to means for preventing the incrustationof boilers, particularly locomotive boilers, by the deposit of scale or other mineral matter from the water in the generation of steam, and its primary oblect is to provide a device adapted for appl1cation to a locomotive tender, whereby quan-tlties of a water-softening or incrustation-preventing agent may be automatically supplied to the feed water at required intervals.

A further obj ectof the invention is to provide an apparatus, controlled automatically by the level of the water in the tender tank, whereby specified amounts of a material or compound, held in containers, may be supplied to and dumped into the water 'in the tank at proper intervals, and an excess-supply of the compound or material to the tank avoided.

A still further object of the invention is to provide, an apparatus of the character defined which will be controlled solely by the level of the water in the tank, thus obviating the necessity of supplying auxiliary power to operate the same.

The invention consists in the features of construction, combination and arrangement of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a vertical longitudinal section through the device and a portion of a locomotive tendertank, showing the position of the parts when the water is at its minimum level, and one of the containers in position to be dumped upon the supply ofwater to the tank Fig. 2 is a similar view showing the said container dumped and the parts of the apparatus held in locked position to prevent feed motion of the remaining containers of the series; Fig. 3 is a vertical transverse section through the parts as illustrated in Fig. 1; Fig. 4; is a fragmentary perspective view of the receiver; and Fig. 5 is a detail perspective view of the latch and co-acting trip member.

Referring to the drawings, 1 designates a Water supply tank, such as the tank of a locomotive tender, the top of which, in accordance W1th,my lnventlon, 1S provlded with an opening 2 and a suitable supporting bracket or upright 8. Supported upon the top of the tank is a casing 4 which may be of any preferred construction, and which. is provided with a removable lid or cover 5, secured in any closed position, in practice, in any preferred manner. Fitted within and extending through the opening 2; is areceiv'er, chute or trough 6, comprising an oblong rectangular body having an open sloping top 7 and a perforated or grated bottom 8. The receiver projects downwardly into the tank below the maximum water line and upwardly into the casing i and is provided at its upper end with a supporting hook 9 to engage overv the upright 3, whereby it is removably sustained in position.

' Arranged within the casing l is a suitable number or series of receptacles or containers 10, in each of which is placed a suitable amount or .charge of the compound or material which is to be supplied to the water in the tank to soften the same or to otherwise act thereon to prevent the deposit of mineral or other matter contained inthe water within'the tank and boiler or tocause the deposit of any foreign matter contained inthe water within the tank to prevent its passage to the boiler. Each of these containers or receptacles consists of an elongated oblong rectangular vessel open at the top and-having a sloping or inclined bottom 11. .Ilach of said containers is-v provided at'its opposite sides with projecting guiding and stop pins 12, arranged about midway of the length of-said container, and adjacent to the front wall thereof. Each of said containers has also secured to its rear wall a bar or plate 13 which projects below its inclined bottom 11 and extends transversely thereof and is provided with laterally extending guide andstop pins 14. The inclined bottoms of the series of containers 10, of which any suitable number may be employed, rest upon an inclined trackway extending downwardly toward the lower portion of the sloping upper correspondingly inclined to't rails and slope also toward the sloping per end or are upper stop rails or fiangesz which are feed motion and held from upward move- 1 ment or displacement under the jars and vibrations of the tender when the locomotive is running.

The construction and arrangement of the parts described is such that when theforward container contacts with the @bracket 3 the stop pins 12 of said containerwill pass beyond the lower ends of the flanges 17,while the lugs 14 of the cross bar 13 of said con tainer will at the same time have passed beyond the lower ends of the flanges Not the rails 15, whereby when said container is elevated it will tilt upon the lower edge of the sloping mouth 7 of the receptacle 6 and be dumped in an inverted positioninto the said receptacle and upon the bottom 8 thereof, as clearly shown in Fig. 2, so that the contents of said container will be dis charged-through the grated bottom 8 into the water in the tank. 1. Y v The mechanism for controlling the series of containers in regular order, and at proper intervals, is controlled by the level of the water in the tank 1. This mechanism comprises a vertically movable float 18, adapted to rise and fall in the water, said float being provided with guide sleeves 19 engaged in a pair of spaced guide rods or bars20 depending from the top of the tank 1 and connected at their lower ends by a cross bar 21 reinforced from the tank by suitable braces 22. The float is also provided with a bracket arm 23 terminating in a guide sleeve 24, through which projects a vertically movable -or reciprocating lifting or dumping rod 25 carrying a bail-shaped head or engaging member 26 at its upper end, which is movable through guide openings 27 in the top of the tank and pro3ects into the casing 4 at a point in advance of the lower end of the rails 16. A nut or other suitable abutment 28 is adjustably mounted on the rod-25 and rests upon the guide sleeve 24, whereby the rod is adapted to be moved upwardly with the float, and the position of the float with respect to a particular portion of the rod may be varied.

The bracket arm 23 is also provided with an eye 29 for the passage of the threaded upper end of a rod 30, the lower end of which carries a conical trip member 31 slidably engaging the rod 25, the said rod 30 being adjustably secured in position by nuts 32. lit will thus be understood that the float mes es and trip member may be adjusted vertically with respect to the rod, and the trip memher with respect to both the float and rod, so that the operation of said parts may varied, according to any variation which -may occur with regard to the desired maaimum level of the water in the tank 1, with the efiect of securing a reliable operation of the dumping mechanism at the required periods.

Jlhe lower end of the lifting or dumping rod 25 is notched to provide a latched re cess or shoulder 33 adapted to be engaged by a hooked end 34; of a latch member pivoted to a bracket arm-36 secured to bar 21, which bracket arm also carries guide sleeve 37 through which the lower end of the lifting or dumping rod is mov able, the construction being such that when the dumping rod is shifted to the limit a its upward movement it will be automatically' engaged;by the latch 35, the hooked endof which seats in the recess 33 and under the shoulder formed thereby, and thus locks the lifting rod from descent. An adjustable weight 38 or its equivalent is provided for moving the latch into operative position. when the notch or recess comes into position for engagement thereby, and a curved trip arm 39 is provided upon the hooked end of the latch for engagement with the trip member 31 for the automatic retraction of the latch upon the descent of the float and for maintaining the latch in retracted position during the lowering of the dumping rod and until it is again elevated into dumping position. The trip arm 39 is curved or cam-shaped so as to be properly engaged by the tapered or conical trip 111631;

her 31, as illustrated particularly in li igl.

In the operation of the device, the containers are filled with the desired compouz.

or substance which is to be supplied to water and then are arranged in tandem or der, as shown inl ig. 1, upon the inclined trackway, with the stop pins. and lugs of the first or lower container clear of the stop flanges or rails, while the stop pins and lugs of the other containers of the ser es are in engagement with the stop and guide rails, the first container of the series being thereby in position to be elevateclmidumped. Fig. 1 shows the position of the parts when the water has passed below its minimum level and the tank should be replenished, from which it will be seen that the baitshaped head 26 of the lifting rod is disposed beneath the first container of the series and. the float and rod are at the limit of their downward movement. When the tank is replenished with water to bring the water therein up to the'normal level the float rises and in so doing elevates the lifting or duniping rod until the trip device 31 clea rs the isengaged by the latch device, as shown in Fig. 2, whereby the rod is locked from downward movement. On its upward movement, the rod comes in contact with and ele-.

vates the first container of the series, which is thereby raised until its lugs 14 engage the stop rail 17, whereupon the container is tilted forwardly and downwardly and dumped into the receiver 6 with its open end downward, whereby its contents are dis charged through the grated bottom 8 of said receiver into the water in the tank 1. The dumping rod is held locked and elevated, so as. to lie in the path of the next succeed; ing container and to hold the containers from forward feeding movement While the Water in the tank remains at its normal level, or until the Water descends to a point at which a replenishing of the tank is required. The float gradually descends with the water and when the water reaches its minimum level the trip device 31 engages the trip arm 39 and retracts the latch 35, thus releasing the lifting rod 25 which again drops by gravity to the position shown in Fig. 1, ready for a repetition of the operation above described to lift and dump the second container of the series into the receiver to supply another charge of the compound or material to the water. When the rod descends, the series of containers, being unrestrained from movement, feed downwardly, and these successive actions ofdumping the container, holding the remaining containers from movement, releasing the containers for movement and resetting the dumping rod for action, and actuating the dumping rod to dump a container, are automatically carried out at properly timed periods by the level of the water in the tank,- whereby a proper proportion of the comound or material, and no more, will be suplied to .the water at the times needed. When all the receptacles are empty, the receiver containing the same may be Withdrawn from the tank and casing, the containers removed therefrom and refilled, and the parts again placed in position for operation. The receiver is made of suficient depth and width so that a number of con tainers may be received therein and the contents thereof permitted to drop by gravity through a grated bottom without any interference, it being understood that any portion of the compound which maybe retained by any containers within the receiver will be dislodged through the rocking motion of the tender, so that a reliable fed of all of the compound or material to the water will be secured. By adjusting the iioat and movable trip member 31 with relation to the lifting rod, the action of the rod may be governed according to the intended maximum and minimum levels of the water in a reliable and eilicient manner and as occasion way toward the receiver, means may es-a the anrlicatinn at the mam tien to, di er nt kin or ze o e d r tanks A impo t. advantage arising from h cons ru tion de s at the supply of the water itself governsand effects the operation of the apparatus, thus obviating the use of power appliance for the pur- PQ$ I claim as my invention: v p 1.
